C# 14 spans, Minimal APIs, and EF Core gains
A varied .NET roundup with C# 14 span improvements, Minimal API migration advice, EF Core tuning, MediatR logging, Azure, and more.
Jasen's top three picks
- 1 Spans Got Easier in C# 14
Medium
C# 14 span conversions are the sort of small language change that can remove a lot of ceremony.
- 2 VS Code Live at GitHub Universe - Day 1 - Live Coding with Copilot!
YouTube
The GitHub Universe live coding session is more about the workflow than the demo, and that’s useful in itself.
- 3 🌐 Understanding WCF Service in .NET with Example and Benefits
C# Corner
The Minimal APIs migration post stands out because it tackles auth and filters, not just happy-path routing.
Editor's note
I kept this one deliberately mixed: language features, architecture, performance, and a few legacy corners all showed up together. The C# 14 span piece and the EF Core optimization challenge are the kind of practical reads that can change day-to-day code, while the Minimal APIs migration post is useful if you’re untangling a real app. The Unity and old-school WebForms items are also a reminder that the .NET world is still wider than the newest templates.
